Smart bracelet to monitor his activity

This bracelet is not too much to bear (casually, it may influence). It's bad. Then it records everything. The number of steps, calories burned. For me, using smartphone applications (RunKeeper style), I appreciate the autonomy and the fact of not having to systematically drain the battery of my laptop. The battery takes only two to three days instead of piecemeal announced. Too bad but for me Sunday sports and uses the bracelet in transport (by pure curiosity and fun), that's enough. Too bad there is no gps tracking (or recording positions), finally, I think it is better to prefer buying a smart watch with the purchase of your next smartphone (since for activities other than walking or running, you have to buy a special belt to monitor the heart rhythm).

The graphics on the phone or the computer are in line with what is done in the market.
